North Korea has undertaken an artillery drill on Friday, and the shell firing sounds could be heard on the bombarded island of Yeonpyeong. There was an alert issued in South Korea after the firing sounds were heard, as a result this is also a warning to South Nation and as well as to their US counterparts who have sent an Aircraft Carrier to the Korean waters.

China on the other hand who is the only major ally to the North Koreans has warned that it will also take strict action if there is any sort of battle activity in its special economic zone waters. China had earlier summoned a warning to the US, when the US Navy and South Korea were having war games in its waters.

This is the first firing heard since the attack on South Korea, and Korean army has positioned in more troops on its Yeonpyeong island. Yeonpyeong is one of the disputed areas of North and South Korea and there has always been an international debate between these countries.
